save icon is not floppy disk

I am reading the Ubuntu Manual rev. 788 (as part of the "Show us ya bugs" initiative), and in Chapter 3, on p. 74, I believe I have discovered an incorrect information bug. The Manual states, "Finally, click on the Save button on the toolbar to save this
new event (the button looks like a floppy disk, and is the first button on the toolbar)." However, the save icon is a hard disk, not a floppy.
